Real-time video conference chat filtering using machine learning models

ABSTRACT

In various examples, as a user is speaking or presenting content during an online video conference, the data stream may be processed to generate a textual representation (e.g., transcript) of the audio and/or information relating to the video. The textual representation and/or video related information may then be processed to determine a context or one or more topic(s) of discussion. Based on the determined context/topic(s), a corresponding neural network(s) may be selected. Once a neural network has been selected, comments may be retrieved from a chat feature of the application and applied to the neural network. The neural network may then output data to indicate the relevance of the comments to the determined discussion topic. Based on the relevance of the comment, the comment may be allowed, prioritized, deleted, de-emphasized, or otherwise filtered in the chat feature.

CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation of U.S. patent application Ser. No. 17/085,618, filed Oct. 30, 2020 which is incorporated herein by reference in its entirety.

BACKGROUND

Hosts of multi-party video streams—such as online video conferences, game streaming services, video streaming services, etc.—often enable a chat and/or comment feature during a presentation, stream, or video conference to allow attendees to communicate textually—e.g., in the background, while a presentation is taking place. For example, a host (e.g., presenter, teacher, moderator, sharer, etc.) may mute all attendees or viewers of an online video stream, but enable a chat and/or comment box to allow users to type messages to the host or other attendees of the video stream. However, these chat boxes can fill up with off-topic or inappropriate comments. As a result, these off-topic or inappropriate comments may be distracting to the host or attendees, and may result in a diminished user experience. Further, some on-topic comments may be missed by the host or other attendees due to a large volume of off-topic comments.

Traditional systems may provide hosts with the ability to disable chat boxes and/or block all comments associated with a video stream. Alternatively, hosts in these traditional systems may enable only specific users to comment during a video stream. For example, a host may restrict the option to comment in the chat and/or comment box such that only subscribers to a host's channel or service can comment. However, hosts often want to interact with their audience and appreciate on-topic comments from attendees, which may be blocked by these traditional systems. Other traditional systems may provide hosts with a simple word filter to scan and remove some comments as they are submitted. However, these systems merely search for specific words or strings of words—e.g., profane or harassing comments—and remove or overwrite them regardless of context, which still allows off-topic or harassing comments that may not be identified by the word filter to be entered into the chat and/or comment box.

SUMMARY

Embodiments of the present disclosure relate to topic-based real-time video conference chat filters. Systems and methods are disclosed that determine the relevance of text entered into a chat feature by applying the text to a neural network that corresponds to a discussion topic in an application.

In contrast to conventional systems, such as those described above, the present system receives a data stream associated with an application—such as from a host device during an online video conference, video stream, game stream, and/or the like to determine a context—such as a frame of reference, relevant time period, or topic of a discussion—that corresponds to the data stream and to determine relevant content to allow and/or display in a chat feature of the application. According to some examples, as a user is speaking or presenting content during an online video conference, the data stream (e.g., audio data, video data, metadata, etc.) may be processed to generate a textual representation (e.g., transcript) of the audio and/or information relating to the video of the online video conference. In some embodiments, the textual representation and/or video related information may then be processed to determine a context—such as a frame of reference, relevant time period, or topic of a discussion—in a conference, a topic of a video stream, a topic of a game stream, and/or the like. Based on the determined topic(s), a corresponding neural network(s) may be selected. For example, if a teacher is discussing Macbeth during a virtual learning video conference, a neural network that is trained using content relating to Macbeth may be selected based on processing a transcript of the discussion to determine that the user is discussing Macbeth. Once a neural network has been selected, comments may be retrieved and/or intercepted from a chat feature (e.g., a chat box) of the application and applied to the neural network. The neural network may then output data to indicate the relevance of the comments to the determined discussion topic. A corresponding tag may then be associated with each of the comments. For example, comments determined to be relevant may be labeled as ‘on-topic’ and comments determined to be irrelevant may be labeled as ‘off-topic’. Based on the relevance of the comment, the comment may be allowed, prioritized, deleted, de-emphasized, or otherwise filtered in the chat feature. As a result, irrelevant comments may be blocked from being displayed to the users, which may allow the users to focus on the material being discussed in the virtual learning video conference.

In some embodiments, after generating the transcript and/or the video related information, the system may process the information to determine whether the transcript includes a trigger phrase and/or the video information includes a triggering action. Based on the determined trigger phrase or action, one or more response options may be determined. Based on determining that the teacher asked a “yes or no” question (e.g., a trigger phrase), the system may only accept “YES” or “NO” comments entered into the chat feature. In another example, based on the determined question, the system may generate and display a selection box that includes selection buttons that allow students to only choose “YES” or “NO” answer options. Advantageously, the user may collect responses from attendees in an organized manner without enabling an open chat feature.

DETAILED DESCRIPTION

Systems and methods are disclosed related to topic-based real-time video conference chat filters. Although primarily described herein with respect to video streaming implementations, this is not intended to be limiting, and the systems and methods of the present disclosure may be implemented in any implementation for filtering textual data. For non-limiting examples, the systems and methods described herein may be implemented for game streaming applications, video conference applications, virtual learning applications, social media content sharing application, video sharing applications, and/or the like.

In some embodiments, a chat management system may receive a data stream (e.g., audio data, video data, metadata, etc.) associated with an application, such as from a host device during an online video conference, video stream (or playback), game stream, and/or the like. The application may be executed locally and/or may correspond to a streaming application executed within a cloud computing environment. According to some examples, as a user is speaking or presenting content during an online video conference, the data stream may be processed to generate a transcript of the audio and/or information relating to the video. In some embodiments, the data stream may be applied to a natural language processing algorithm (NLP) to generate a transcript of the audio and/or information relating to the video.

In some embodiments, the transcript and/or video related information may then be processed to determine a context (including, without limitation, a frame of reference, or topic) of a discussion in a conference, a video stream, a game stream, and/or the like. The context of the discussion may be determined by processing the transcript to determine one or more keywords associated with a determined context. Further, data representative of the transcript may be applied to a neural network to compute data indicative of the discussion context. Additionally or alternatively, computer vision, machine learning, and/or other methods may be employed to support determining a context or topic based on analysis a video. For example, where a portion of a video may not include any spoken words—such as a stream of gameplay—and/or a transcript may be insufficient for determining a context, frames of the video may be analyzed to extract information from the frames of the video, which may be processed (e.g., by a neural network) to determine a context of the video. Moreover, in further examples, the topic may be determined, at least in part, based on metadata (e.g., title, description, host, creator, and/or author) associated with the data stream. Combinations of any of the above are be included within the scope of the implementations of the present disclosure.

Based on the determined context(s), a corresponding neural network(s) may be selected. The corresponding neural network may be determined from a store of neural networks that may include any number of neural networks, each associated with a context. In some embodiments, the store of neural networks may be organized in a hierarchical data structure, wherein the scope of a neural network in a parent node may be more broad when compared to the scope of a neural network in a child node. For example, a neural network in a parent node of the hierarchical data structure may be trained generally on the work of William Shakespeare, while a child node to the parent node may be trained more specifically on a particular work of Shakespeare's, such as the play Macbeth. Based on a confidence level for a given topic (e.g., determined using keywords, a neural network, or a combination thereof), a more focused or granularly trained neural network may be selected in addition to, or instead of, the broader neural network. By way of further example, if a teacher is discussing Macbeth during a virtual learning video conference, the system may select a first neural network that is trained using content broadly relating to Shakespeare as well as a second neural network that is trained using content specifically relating to Macbeth. As some users may prefer that chat discussions be highly related to the topic of discussion, user settings may be provided to allow a user to establish preferences related to neural network selection. As such, and continuing with the example above, the teacher discussing Macbeth may select, via a user interface, an allowed breadth level that may be used to only allow comments specifically related to Macbeth and filter out comments generally related to Shakespeare. In such an example, the system may select only the neural network that is more narrowly focused on Macbeth.

Once one or more neural network(s) has been selected, textual data may be retrieved from a chat or comment feature of the application and applied to the neural network. For example, when a user types a comment into a text input field of a chat feature and selects to post the comment, prior to being displayed, the comment may be intercepted by the system and textual data associated with the comment may be applied to a selected neural network that corresponds to a topic of discussion. The neural network may then output data to indicate the relevance of the comment to the determined discussion topics, whether the comment is offensive or inoffensive, and/or information related to other characteristics of the textual data. A corresponding tag may then be associated with each of the comments. For example, comments determined to be relevant may be labeled as ‘on-topic’ and comments determined to be irrelevant may be labeled as ‘off-topic’. Additionally or alternatively, the neural network may output data to indicate whether the comment is offensive, harassing, profane or otherwise inappropriate for the topic of discussion.

Based at least in part on the determined relevance of the comment, a display option may be determined for the comment. For example, within the chat feature of the application, the comment may be displayed, prioritized relative to the relevance of other comments, deleted/removed such that the comment is not displayed, de-emphasized, or otherwise filtered. In some embodiments, a filter may be applied only to a portion of the comment. For example, an irrelevant portion of a comment may be deleted or obscured, while the relevant portion of the comment may be displayed within the chat feature. As a result, irrelevant comments may be blocked from being displayed to the users, which may allow the users to focus on the material being discussed in the current instance of the application.

In some embodiments, after generating the transcript and/or the video related information, the system may process the information to determine whether the transcript includes a trigger phrase and/or the video information includes a triggering action. A trigger phrase may be a single word, a single sound, a string of words, and/or a sound pattern. A trigger phrase may be determined based on comparing words from the transcript to a trigger phrase dictionary that includes a set of trigger phrases and determining that one or more words from the transcript correspond to one or more trigger phrases. For example, a user may say, “QUESTION, who did their homework this weekend?” In this example, the word “QUESTION” may be the trigger phrase that the user may state to trigger the system to capture the words following the trigger phrase to perform some action (e.g., generate a prompt to respond in the chat feature based on the question). Additionally or alternatively, data representative of the transcript may be applied to a neural network to compute data indicative of a trigger phrase. A triggering action may be a gesture performed by a user or an input received by the system via a peripheral device. For example, a user may perform a gesture in the air that is captured and processed via computer vision or gesture recognition techniques and/or the user may actuate a button on a presentation remote or graphical user interface to operate as the trigger.

Based on the determined trigger phrase or action, one or more response options may be determined. A response option may be a set of appropriate and/or relevant responses. Further, one or more responses within a chat feature that do not correspond to the one or more response options may be filtered out. For example, a teacher may ask his/her class, “Did you read ‘Macbeth’ over the weekend?” Based on determining that the teacher asked a question (e.g., a trigger phrase), the system may only accept “YES” or “NO” comments entered into the chat feature. In some embodiments, a graphical element may be generated and populated that corresponds to the one or more response options within the chat or comment feature. For example, based on the determined question, the system may generate and display a selection box that includes selection buttons that allow students to only choose “YES” or “NO” answer options in response to the teacher's question as to whether the students read Macbeth over the weekend.

In some embodiments, the one or more selected neural networks corresponding to a topic of discussion may be used in conjunction with a trigger phrase to generate a selection box with several potential answers. For example, a teacher in a virtual learning video conference may ask, “Who is the main character in Macbeth?” Based at least in part on the question and a selected neural network trained on information related to Macbeth, the system may generate a selection box with four names—one being the main character of Macbeth—from the source material (e.g., the play “Macbeth”) or related source materials such as other works from the same author or the author's contemporaries (e.g., other works from Shakespeare).

With reference to FIGS. 1A and 1B, FIGS. 1A and 1B depict data flow diagrams corresponding to processes 100A and 100B for chat management systems, in accordance with some embodiments of the present disclosure. It should be understood that this and other arrangements described herein are set forth only as examples. Other arrangements and elements (e.g., machines, interfaces, functions, orders, groupings of functions, etc.) may be used in addition to or instead of those shown, and some elements may be omitted altogether. Further, many of the elements described herein are functional entities that may be implemented as discrete or distributed components or in conjunction with other components, and in any suitable combination and location. Various functions described herein as being performed by entities may be carried out by hardware, firmware, and/or software. For instance, various functions may be carried out by a processor executing instructions stored in memory. In some embodiments, components, features, and/or functionality described herein with respect to FIGS. 1A and 1B may be executed using example content streaming system 500, example computing device 600, example data center 700, or a combination thereof. For example, the processes 100A and 100B may be executed locally and/or in a cloud computing environment—e.g., using the example content streaming system 500 and/or one or more example data centers 700. Although illustrated separately, the processes 100A and 100B, in embodiments, may be executed together. For example, chat entries and/or comments may be filtered out using the process 100A while graphical elements for predefined response options may be populated in a chat or comment feature using the process 100B.

Turning to FIG. 1A, FIG. 1A illustrates an example data flow diagram for a process 100A that may be executed within a chat management system. The chat management system may include a chat manager 102, which includes a transcript generator 106, a topic (or context) determiner 108, and a neural network store 110. The process 100A may further include stream data 104, a selected topic neural network 112, textual data 114, an application 116, and a comment display option 118.

In operation, the chat manager 102 may receive the stream data 104 from the application 116, which may include a chat feature and/or comment feature and be executed locally on a user device and/or may correspond to a cloud-based application executed within a cloud computing environment. The stream data 104 may include data corresponding to words spoken by a user or data corresponding to content presented during an online video conference, video stream, game stream, video playback, and/or the like. In some embodiments, the stream data 104 may correspond to content that is audio-only, video-only, or a combination thereof. Although referred to as stream data 104, this is not intended to be limiting, and in some embodiments the stream data 104 may not be streamed. For example, the stream data 104 may be downloaded, played back, and/or otherwise received without streaming. In embodiments where the stream data 104 is streamed, the stream may correspond to a live stream and/or a previously recorded or stored stream.

The stream data 104 may be passed to the transcript generator 106, and the transcript generator 106 may generate a transcript based on the stream data 104. In some embodiments, the transcript generator 106 may use natural language processing (NLP) to generate a transcript from the stream data 104. For example, a machine learning model(s), a neural network(s), a NLP algorithm, and/or another type of NLP algorithm may be used to generate a transcript from the stream data 104. In some embodiments, in addition to or alternatively from using NLP to process audio data of the stream data 104, video data of the stream data 104 may be processed using a computer vision algorithm(s), a machine learning model(s), a neural network(s), and/or another type of algorithm to determine contextual data, metadata, and/or other information about content. As such, the transcript generator 106 may generate the transcript to include textual data, contextual data, metadata, and/or other data types based on audio data, video data, and/or metadata from the stream data 104.

The transcript (or other textual representation) may then be processed by the topic determiner 108 to determine one or more topics of discussion in a conference, a seminar, a video stream, a game stream, and/or the like. In some examples, the topic determiner 108 may determine the topic of discussion by determining one or more keywords associated with a topic from the transcript, applying data representative of the transcript to a neural network to compute data indicative of the topic, by employing computer vision to analyze frames of video included in the stream data 104 to determine the topic, and/or by analyzing metadata (e.g., title, description, host, creator, and/or author) associated with the stream data 104.

Using the determined topic(s), the chat manager 102 may access the neural network store 100 to select one or more topic neural network(s) 112, each associated with a topic(s). As discussed herein, the topic neural network(s) 112 may be associated with entirely different topics/contexts and/or may be associated with similar topics but with varying scope. For example, the chat manager 102 may select a parent neural network trained on Shakespeare as well as a child neural network trained on Macbeth. While overlap may exist between the topics associated with neural networks, the scope of the child neural network may be more granular than that of the parent neural network.

In some embodiments, the topic neural networks 112 may be trained using training textual data sets (or training video sets, where video is used as input to the topic neural network 112) that relate to associated topics. For example, in the Macbeth example, sample text strings (e.g., retrieved from comments or chats, created for training purposes, and/or the like) may be used as training data. The sample text strings may have associated ground truth data that indicates what the topic neural network 112 should predict—e.g., relevance, appropriateness, etc. As such, data representative of the text strings may be applied to the topic neural network 112, and the topic neural network 112 may compute outputs that indicate the relevance, appropriateness, etc. The outputs may then be compared to the ground truth data using one or more loss functions, and the parameters (e.g., weights and biases) of the topic neural network 112 may be updated using one or more optimization functions (e.g., gradient descent, momentum, adagrad, etc.) until an acceptable level of accuracy is achieved.

Transfer learning may be used in some embodiments. For example, one or more topic neural networks 112 may be trained—at least preliminarily—based on training data for one topic, and the topic neural network 112 may be updated or fine-tuned based on training data from of another topic. As such, in the Macbeth example, the topic neural network 112 may be trained on Shakespeare (or even more broadly, on literature), and the pre-trained topic neural network 112 may be updated (or additionally trained) on training data associated with Macbeth. As another example, a topic neural network 112 may be trained for Macbeth, and then may be retrained or updated for Julius Caesar.

In some embodiments, in addition to or alternatively from a topic neural network 112 being selected based on a determined topic from the transcript, a user (e.g., speaker, presenter, content generator, etc.) may select a topic neural network(s) 112 from a store of topic neural network(s) 112 to be used during an instance of the application. For example, a teacher may select a topic neural network 112 that corresponds to a current subject matter he or she is teaching, a game streamer may select a topic neural network 112 corresponding to the type of game (e.g., first person shooter, basketball, strategy, etc.) and/or game title that the user is playing and/or streaming, a video content sharer may select a topic neural network 112 corresponding to a topic of the shared content (e.g., a cooking video, a “how-to” segment, an education series, etc.), etc.

Once the topic neural network(s) 112 have been selected (e.g., automatically by the system and/or manually by a user), the chat manager 102 may retrieve textual data 114 (and/or other data types, such as video and/or metadata) from the application 116. In some embodiments, chat comments input into the chat feature of the application 116 corresponding to the textual data 114 may be intercepted by the chat manager 102 (e.g., via one or more application programming interfaces (APIs)). The textual data 114 may be applied to the topic neural network(s) 112 and the topic neural network(s) 112 may output data to indicate whether the textual data 114 (and/or other data types) is relevant, and/or appropriate, or irrelevant, offensive, harassing, profane, otherwise inappropriate for the topic of discussion, or a combination thereof, etc.

Based on the output data from the topic neural network(s) 112, a comment display option 118 may be determined for a comment(s) corresponding to the textual data 114. For example, the comment(s) may be displayed, prioritized relative to the relevance of other comments, deleted/removed/filtered out from the chat feature included in the application 116 such that the comment is not displayed, de-emphasized, or otherwise filtered. In some embodiments, user preferences may be applied to the chat manager 102 to determine whether the comment display option 118 for a relevant comment indicates to simply allow the comment to be displayed or to prioritize, emphasize, and/or highlight the comment. Similarly, the user preferences may indicate whether a comment, or portion of a comment should be deleted, de-emphasized, or otherwise filtered. Each of the options for the comment display option 118 may be based on a confidence value for the relevance of a comment output by the topic neural network(s) 112. For example, if the topic neural network(s) 112 processes textual data 114 and outputs a confidence value that exceeds a threshold value indicating that the comment is irrelevant (or inappropriate, etc.), the comment associated with the textual data 114 may be deemphasized, removed, etc.

Turning to FIG. 1B, FIG. 1B illustrates a data flow diagram corresponding to a process 100B for an example chat management system. The chat management system may include chat manager 102B, which includes a transcript generator 106, a trigger determiner 120, a trigger dictionary 122, and a response option generator 122. The process 100B may further include stream data 104, application 116, and a response option 126. The application 116, stream data 104, and/or transcript generator 106 may be similar to those described with respect to FIG. 1A. However, depending on the embodiment, variations of these features and/or functionality may exist.

In operation, the chat manager 102B may receive the stream data 104 from the application 116, which may include a chat feature and be executed locally on a user device and/or may correspond to a cloud-based application executed within a cloud computing environment. Similar to the description with respect to the process 100A, the stream data 104 may be used by the transcript generator 106 to generate a transcript. Using the generated transcript, the trigger determiner 120 may determine that the transcript includes a trigger phrase and/or action (e.g., based on textual, contextual, video, metadata, and/or other data from the transcript). A trigger phrase may be determined based on comparing words from the transcript to the trigger dictionary 122, which may include a set of trigger phrases and/or actions (e.g., a single word, a single sound, a string of words, a sound pattern, a hand gesture, etc.), and determining that data from the transcript corresponds to one or more trigger phrases or actions. Additionally or alternatively, data representative of the transcript may be applied to a neural network used by the trigger determiner 120 to compute data indicative of a trigger phrase or trigger action.

In some embodiments, such as where the trigger determiner 120 may determine a trigger action (e.g., a gesture performed by a user or an input received by the system via a peripheral device) based on processing stream data 104, the stream data 104 may include data representative of a user performing a gesture in the air that is captured and processed via computer vision or the stream data 104 may include data representative of input from a user pressing a button on a presentation remote. This data may be processed by the trigger determiner 120 to determine a trigger action.

The response option generator 124 may receive the trigger phrase and/or trigger action. Based on the determined trigger phrase or action, the response option generator 124 may process additional data from the stream data 104—e.g., a question that follows the trigger—to determine one or more appropriate and/or relevant response option(s) 126. For example, a teacher may ask his/her class, “Did you read ‘Macbeth’ over the weekend?” Based on the trigger determiner 120 determining that the teacher asked a question (e.g., a trigger phrase), the response option generator 124 may determine that the only acceptable response options are “YES” or “NO”. In some embodiments, the response option generator 124 may generate a graphical element for displaying the response option(s) 126 via the application 116. For example, based on the trigger phrase, the response option generator 124 may generate, and the application 116 may display, a selection box that includes selection buttons that allow students to only choose “YES” or “NO” response options to answer the teacher's question as to whether the students read Macbeth over the weekend. The selection box may be generated within a chat feature of the application 116, within another area of an attendee's display, and/or may be provided as a notification to a client device of an attendee, such as those described in FIG. 7 . In some embodiments, the response option generator 124 may generate a selection box with several potential answers for attendees to select.

Turning to FIG. 2 , FIG. 2 is an example user interface 200 for a video conference application, in accordance with some embodiments of the present disclosure. The example user interface 200 includes an application viewing panel 202, a host streaming window 204A, a host 204B, a plurality of participant streaming windows 206, and a chat box 208. The chat box 208 includes an input field 210 and illustrates a response selection box 212, as well as several user comments 214, 216, and 218.

In operation, as the host 204B is speaking or presenting content during an instance of the video conference application, stream data 104 (e.g., audio data, video data, etc.) may be processed to determine a topic of discussion. Based on the determined topic(s), a corresponding topic neural network(s) 112 may be selected to manage comments input into the chat box 208. For example, if the host 204B is discussing Macbeth during the instance of the video conference application, one or more topic neural networks 112 trained using content relating to Macbeth (or more broadly to Shakespeare, or even more broadly to literature) may be selected based on processing a transcript of the discussion to determine that the host 204B is discussing Macbeth. Once the topic neural network 112 has been selected (e.g., automatically by the system and/or manually by a user, such as the teacher), comments input into the input field 210 may be retrieved and/or intercepted from the chat box 208 and applied to the one or more selected topic neural networks 112. Based on the relevance of a particular comment, the comment may be allowed, prioritized, deleted, de-emphasized, or otherwise filtered in the chat box 208. For example, the host 204B may ask the question, “Who is the main character in Macbeth?” In response, participants to the instance of the video conference application may input comments 214, 216, and 218 into the input field 210. Prior to displaying the comments in the chat box 208, each of these comments may be applied to the selected topic neural network 112 to determine the relevance (and/or appropriateness) of the comments. Based on the relevance, a display option may be determined. For example, comments 216 and 218 may both be considered relevant and, thus, may be displayed in the chat box 208. Further, comment 218 may be determined to be more relevant (e.g., more on topic) when compared to comment 216. As such, comment 218 may be emphasized and/or moved above comment 216 in the chat box 208. Comment 214 (e.g., reciting “Who is playing GAME X tonight?”) may be determined to be irrelevant and, as such, may be obscured in the chat box 208. In some embodiments, comments that are obscured or filtered out during the instance of the video conference application may be recorded and sent to the host 204B after the termination of the instance of the video conference application. Advantageously, the host 204B may review these comments at a later time and answer any questions as needed. In some embodiments, the moderator, teacher, or other user may be presented with the irrelevant and/or relevant chat entries (e.g., some or all of the chat entries) such that the user may allow them, disallow them, prioritize them, etc. For example, the user may be presented with the text and/or semantic information related thereto (e.g., irrelevant but appropriate, or relevant but inappropriate, etc.), and may make a final determination as to the presentation of the text.

In some embodiments, based on determining that host 204B asked a question (e.g., a trigger phrase), the selection box 212 may be generated and displayed in the chat box 208. For example, the host 204B may ask the participants, “Did you do your homework?” Based on this question, the selection box 212 may include selection buttons to allow the participants to only choose “YES” or “NO” answer options. Participant selections may be recorded, sent to, and/or displayed for the host 204B.

Now referring to FIGS. 3 and 4 , each block of methods 300 and 400, described herein, comprises a computing process that may be performed using any combination of hardware, firmware, and/or software. For instance, various functions may be carried out by a processor executing instructions stored in memory. The methods 300 and 400 may also be embodied as computer-usable instructions stored on computer storage media. The methods 300 and 400 may be provided by a standalone application, a service or hosted service (standalone or in combination with another hosted service), or a plug-in to another product, to name a few. In addition, methods 300 and 400 are described, by way of example, with respect to the processes of FIG. 1A and FIG. 1B, respectively. However, these methods may additionally or alternatively be executed by any one system, or any combination of systems, including, but not limited to, those described herein.

FIG. 3 is a flow diagram showing a method 300 for managing comments, in accordance with some embodiments of the present disclosure. The method 300, at block B302, includes generating a textual representation of a data stream associated with an application based at least in part on audio data included in the data stream. For example, as a user is speaking or presenting content during an online video conference, the data stream (e.g., audio data, video data, etc.) may be processed to generate a textual representation (e.g., a transcript) of the audio and/or information relating to the video.

The method 300, a block B304, includes determining a context corresponding to the textual representation. For example, the textual representation and/or video related information may then be processed to determine a context of the discussion in a conference, a context of a video stream, a context of a game stream, and/or the like.

The method 300, a block B306, includes determining a neural network corresponding to the context. For example, based on the determined context(s), a corresponding topic neural network(s) 112 may be selected. The corresponding topic neural network 112 may be determined from a store of neural networks that may include any number of neural networks, each associated with a context or topic.

The method 300, a block B308, includes applying, to the neural network, textual data retrieved from a chat feature of the application. For example, once one or more topic neural networks 112 have been selected, comments may be retrieved from a chat feature of an application and applied to the topic neural network(s) 112.

The method 300, a block B310, includes computing, using the neural network and based at least in part on the textual data, data indicative of a relevance of the textual data to the topic. For example, comments determined to be relevant may be labeled as ‘on-topic’ and comments determined to be irrelevant may be labeled as ‘off-topic’.

The method 300, a block B312, includes determining a display option for the textual data within the chat feature of the application based at least in part on the relevance of the textual data. For example, within the chat feature of an application, a comment may be displayed, prioritized relative to the relevance of other comments, deleted/removed such that the comment is not displayed, de-emphasized, or otherwise filtered. In some embodiments, a filter may be applied only to a portion of the comment. For example, an irrelevant portion of a comment may be deleted or obscured, while the relevant portion of the comment may be displayed within the chat feature.

FIG. 4 is a flow diagram showing a method 400 for managing comments, in accordance with some embodiments of the present disclosure. The method 400, at block B402, includes receiving a data stream associated with an application. For example, a chat management system may receive a data stream (e.g., audio data, video data, metadata, etc.) associated with an application, such as from a host device during an online video conference, video stream, game stream, and/or the like.

The method 400, at block B404, includes generating a textual representation of the data stream based at least in part on audio data included in the data stream. For example, as a user is speaking or presenting content during an online video conference, the data stream (e.g., audio data, video data, etc.) may be processed to generate a transcript of the audio and/or information relating to the video.

The method 400, at block B406, includes determining that the textual representation includes a trigger phrase. For example, after generating the transcript and/or the video related information, the system may process the information to determine whether the transcript includes a trigger phrase and/or the video information includes a triggering action.

The method 400, at block B408, includes determining, based at least in part on the trigger phrase, one or more response options. Based on determining that the teacher asked a “yes or no” question (e.g., a trigger phrase), the system may only accept “YES” or “NO” comments entered into the chat feature.

The method 400, at block B410, includes populating one or more graphical elements corresponding to the one or more response options within a chat feature of the application. For example, based on a teacher asking his/her class a “yes or no” question, the system may generate and display a selection box that includes selection buttons that allow students to only choose “YES” or “NO” answer options in response to the teacher's question as to whether the students read Macbeth over the weekend.

Example Content Streaming System

Now referring to FIG. 5 , FIG. 5 is an example system diagram for a content streaming system 500, in accordance with some embodiments of the present disclosure. FIG. 5 includes application server(s) 502 (which may include similar components, features, and/or functionality to the example computing device 600 of FIG. 6 ), client device(s) 504 (which may include similar components, features, and/or functionality to the example computing device 600 of FIG. 6 ), and network(s) 506 (which may be similar to the network(s) described herein). In some embodiments of the present disclosure, the system 500 may be implemented. The application session may correspond to a game streaming application (e.g., NVIDIA GeFORCE NOW), a remote desktop application, a simulation application (e.g., autonomous or semi-autonomous vehicle simulation), computer aided design (CAD) applications, virtual reality (VR) and/or augmented reality (AR) streaming applications, deep learning applications, and/or other application types.

In the system 500, for an application session, the client device(s) 504 may only receive input data in response to inputs to the input device(s), transmit the input data to the application server(s) 502, receive encoded display data from the application server(s) 502, and display the display data on the display 524. As such, the more computationally intense computing and processing is offloaded to the application server(s) 502 (e.g., rendering—in particular ray or path tracing—for graphical output of the application session is executed by the GPU(s) of the game server(s) 502). In other words, the application session is streamed to the client device(s) 504 from the application server(s) 502, thereby reducing the requirements of the client device(s) 504 for graphics processing and rendering.

For example, with respect to an instantiation of an application session, a client device 504 may be displaying a frame of the application session on the display 524 based on receiving the display data from the application server(s) 502. The client device 504 may receive an input to one of the input device(s) and generate input data in response. The client device 504 may transmit the input data to the application server(s) 502 via the communication interface 520 and over the network(s) 506 (e.g., the Internet), and the application server(s) 502 may receive the input data via the communication interface 518. The CPU(s) may receive the input data, process the input data, and transmit data to the GPU(s) that causes the GPU(s) to generate a rendering of the application session. For example, the input data may be representative of a movement of a character of the user in a game session of a game application, firing a weapon, reloading, passing a ball, turning a vehicle, etc. The rendering component 512 may render the application session (e.g., representative of the result of the input data) and the render capture component 514 may capture the rendering of the application session as display data (e.g., as image data capturing the rendered frame of the application session). The rendering of the application session may include ray or path-traced lighting and/or shadow effects, computed using one or more parallel processing units—such as GPUs, which may further employ the use of one or more dedicated hardware accelerators or processing cores to perform ray or path-tracing techniques—of the application server(s) 502. In some embodiments, one or more virtual machines (VMs)—e.g., including one or more virtual components, such as vGPUs, vCPUs, etc.—may be used by the application server(s) 502 to support the application sessions. The encoder 516 may then encode the display data to generate encoded display data and the encoded display data may be transmitted to the client device 504 over the network(s) 506 via the communication interface 518. The client device 504 may receive the encoded display data via the communication interface 520 and the decoder 522 may decode the encoded display data to generate the display data. The client device 504 may then display the display data via the display 524.
